ELECTREC MOTGR.

SPECIFICATION forming part of Letters Patent No. 388,753, dated August28, 1888.

Application filed June 29,1887. Serial No. 242,840.

To all whom it may concern:

Be it known that I, JOHN BATLEY, of the city and county of Philadelphiaand State of Pennsylvania, have invented an Improvement in ElectricMotors, of which the following is a specification.

My invention has reference to electric motors; and it consists incertain improvements, all of which are fully set forth in the followingspecification, and shown in the accompanying drawings, which form partthereof.

The object of my invention is to employ the direct attraction of thearmatures of a series of electro-magnets to vibrate a series of levers,which in turn cause a rotary movement of the motor-shaft. Theconstruction embodied in my invention is simple and positive, and by aproper number of electro-magnet elements being employed I am enabled tomake the motor of any power desired. The magnets are arranged or coupledin two series, which are adapted to become energized alternately, andeach of the electro-magnets is preferably supplied with electricalcurrent from a separate battery. By cutting out one or more of thebatteries the corresponding electro-magnets are cut out, and hence thepower of the motor may be correspondingly increased or de creased. Animportant feature of my construction is that the operating-levers whichact on the motor-shaft are caused to operate automatically, whethertheir operating-magnets are energized or not, so that all of the movingparts shall maintain a constant relation with each other and all dangerto breakage due to irregular movements becomes obviated.

In the drawings, Figure 1 is a side elevation of an electric motorembodying my improvements. Fig. 2 is a plan View of same showing theconnection with the batteries. Fig. 3 is a perspective view showing theconstruction of thearmatures, operating-levers, and friction-wheels; andFig. e is adia-gram showing the complete circuit between one battery andone operating eleetro-magnet.

A is the frame of the machine.

13 is the central stationary hub or frame, upon which the radiatingeleetro-magnets O and D are secured. These electromagnets O and D arearranged in two series placed (No model.)

I side by side, and preferably staggered. The pole'pieces of thesemagnets are curved, though this is not an essential feature of theconstruction.

E is the motorshaft, which isjournaled in the frame A, and is providedupon each end with a circuit breaking and making commutator, F, and afriction-wheel, H. This frictionwheel is shown in elevation in Fig. land in perspective in Fig. 3, from which the construction may be clearlyunderstood. It consists, essentially, of a notched wheel having thealternate projections I and notches J, the outer surface of theprojections I being eoncentric with the shaft E, to which they aresecured. The forward end of the projections I are provided withprojections t, the purpose of which will be hereinafter explained.

L represents the armatures for the magnets G, and are pivoted at 7r, soas to vibrate to and from the pole, and for effect they are made curvedto tit close to the said pole-piece of the magnet. These armaturesvibrate a series of friction levers, K, provided on their lower partswith adjustable sections K, made adj ustable by means of slots andclamping-screws k, and the lower portions of said parts K are madecurved from 7; as a center,and are adapted to press in contact with theprojections I of the wheels H, so as to form a rolling frictionalcontact. By the vibration of the armatures L it will be seen that thewheel H will be rotated a portion of a revolution, and then thefriction-levers will return to their normal position ready for thenextaction, and so on, returning in the spaces J without contact. Toprevent the shaft E spinning or moving faster than it should with agiven number of vibrations of the levers K, the steps or extensionsi areprovided and are adapted to strike against pins 3 on the lower part ofthe levers K,which pins are adapted to act as stops to arrest prematurerota-tion. The rear ends of the lovers K are provided with extensions72, which are adapted to fit down at the rear of the projections I andinsure a positive thrust to the wheel H at or about the termination of asemi-vibration. From this it will be seen that the wheel H is estoppedfrom running at a too high velocity, and while it is driven byfrictional con tact with the levers a positive thrust is also insuredwith each vibration of the lever. The adjustment of the part K allowsthe wear to be taken up and insures a good firm contact. As shown in thedrawings, there are six sets of magnets in each series, and consequentlysix levers K on each side; but I do not limit myself to any number, asone or more may be used. The levers on one side of the machine arethrown backward, while those upon the other side of the machine arethrown forward, so as to keep up a constant forward motion of the shaftE. To enable the proper action of these levers when so arranged, thewheels H are so set that the projections I on the two wheels arestaggered. (See Fig. 3.)

M represents the armatures for the D series of electro-magnets, and arepivoted at m and secured to the other series of levers K. (See Fig. 3.)The armatures M and L are connected together by means of an arm, L,extending rearwardly from the armature M, and having a slot, m, and intowhich extends a pin, Z, secured to the free end of the armature L. Fromthis it will be seen that as the armature L is attracted to its magnetthe armature M is raised, and vice versa, and in this connection it willalso be observed that the backward movement of the levers K are causedby the attraction of the magnets in the other series to which theybelong, thereby avoiding all the necessity of springs orcounterbalances, and also the employment of but a minimum number ofelectro-magnetic elements.

Grepresents the commutator-brushes, which are arranged in pairs,so thatthe current passes down one brush through the commutator and backthrough the other brush. One of these brushes of each pair leads to itsbattery R and the other brush leads to one of the electromagnets of themotor, and the current returns to the battery by a circuit having aswitch, S. This is clearly shown in Fig. 4., and is simply duplicated inthe plan view, Fig. 2. Each electro-magnet of the two series is providedwith its own complete circuit Q, and its own battery and its own switchS to open the circuit Q. As the commutator F rotates, the magnets of thetwo series are alternately energized, and thereby keep up a continuousaction upon the motor-shaft.

If desired, one or more of the magnets G and D may be simultaneously cutout of action by means of the switches S; but from the nature of theconstruction of the friction-levers and friction-wheels the armature andlevers will continue to work even though their particular magnets arenot energized.
